Redis在Docker容器中没有附加自定义redis.conf文件

Question

我在获取redis以在Docker容器中启动时遇到问题。当我运行

docker-compose up 

我看到输出

Starting redis_redis_1 
Attaching to redis_redis_1 
redis_redis_1 exited with code 0 

之后，我可以运行

docker ps -a 

看到

这是我的码头工人，compose.yml

redis: 
    image: redis 
    command: redis-server /usr/local/etc/redis/redis.conf 
    ports: 
     - "6379:6379" 
    volumes: 
     - /mnt/xvdb/redis/:/usr/local/etc/redis/ 
     - ./redis/redis.conf:/usr/local/etc/redis/redis.conf 

这是详细的输出，我得到：

搬运工日志给我什么

docker logs redis_redis_1 

给我什么

因此，我能够让Redis以我认为是默认配置文件的方式运行。因为第一行显示警告。

Redis must be restarted after THP is disabled.

redis_1 | 1:M 19 Dec 12:30:29.400 * The server is now ready to accept connections on port 6379 

这是什么导致我的redis.conf文件在我原来的问题，我已经覆盖默认命令。

之后我能够检查默认配置文件中的实际内容。

docker exec db00a03fd187 cat /usr/local/etc/redis/redis.conf 

找到我的自定义配置文件被使用。

因此，因为我正在将我的配置文件映射到默认目录，所以我想我会得到那个输出。所以，没有问题。

下面是我结束了我的搬运工，compose.yml文件：

redis: 
    image: redis 
    ports: 
     - "6379:6379" 
    volumes: 
     - ./redis/redis.conf:/usr/local/etc/redis/redis.conf 
     - /mnt/xvdb/redis:/usr/local/etc/redis
